T0 all Iwhom it may concern:

Be it known that L JOHN B. VooELsANG, a citizen of the United States ofAmerica, residing at Webster Groves, in the county of St. Louis, Stateof Missouri, have invented certain new and useful Improvements inDevices for Combining and Emulsifying Substances, of which the followingis a specication.

- This invention relates primarily (but not exclusively) to devices forproducing cream by the intimate admixture of skimmed milk or milk powderwith butter fat or an oil of suitable character; the object of theinvention being to afford a simple, inexpensive, reliable and sanitarydevice for the purpose described.

In the accompanying drawing, wherein like numerals refer to like partsthroughout the several views, Figure 1 is a longitudinal sectional viewdepicting the inferior arrangement of the device and Fig. 2 is a detailsectional view depicting a modification of one of the parts shown inFig. 1.

Referring to the drawing, numeral 1 denotes the body of a sectionaltubeone end of which is coupled as at 2 to a pipe 3 leading to a cooling vat(not shown) and whose opposite extremity is substantially closed lby aplug 4 through which is projected an aperture 5 having flaring ends 6constituting a nozzle.

One of the'extremities of said nozzle com- I municates directly with apipe 7 through which air or steam is supplied under pressure anddisposed adjacent the opposite end ofthe nozzle is a tube 8 which issupported by-an annular member 9 having a rounded edge as at 10 forwhich a seat is provided as at 11' in the coupling 12. It will be notedthat a portion of tube 8 projects within a chamber 13 and that asuction-pipe 14, whose lower end (not shown) is submerged in the mixtureto be emulsied, communiates directly with said chamber. Detachon theinner end of formed of ne one end by a removable screw-plug 17. By wayof modification may employ the finely perforated chamber 16EL shown inFig. 2 in lieu of the wire-mesh chamberof Fig. 1 and in either case thefree extremity of the emulsifying chamber 1s supported against the innersurface of tube 1 by means of lugs 18 formed chamber 16, the

integral with the metal band 19 in which plug 17 is seated.

ln the arrangement of the elements of this device especial attention hasbeen given to the production of an article all of whose parts can bereadily separated and thoroughly cleansed and to this endv it will beappreciated that coupling 12 permits of the easy detachment of thesections of tube 1 and that tube 8, member 9 and the emulsifying chamberare readily separable one from another so that all the parts whereforeign substances might in time find lodgment may be kept in athoroughly sanitary condition.

The operation of the device may be described as follows z-The extremityof pipe 14 being submerged in the vessel containing the mixture which itis desired to emulsify and the said mixture having been agitated andheated, steam or hot air under high pressure is then turned into pipe 7and on passing through nozzle 5 serves to draw said mixture into chamber13 whence it is forced through tube 8 into chamber 16. On reaching theemulsifying chamber the mixture is irst projected against its closed endand the impact is such as to disrupt the fat globules and force themixture backward against the inner surface of said chamber in thedirection of tube 8, whereby a churning effect is produced which serves(especially when the woven wire chamber is used which presents a roughsurface) to further disrupt the fat globules while thoroughly mixing thesubstances employed. The mixture having undergone this treatment, it isnext forced through the wire-mesh of which the preferred emulsifyingchamber is formed, or, if the modification be employed, through theapertures 16b shown in Fig. 2. this resulting in finely dividing the fatglobules and so thoroughly commingling the substances as to producecream which coinpares most favorably with the natural article.

What l claim as new and desire to secure by Letters-Patent is 1. A.device of the character described a pressure-duid supplycomprising atube,

pipe connected therewith, a nozzle disposed between said tube and pipe,a chamber adjacent said nozzle, a pipe extending from said chamberadapted to convey thereto the substances to be emulsied, and a perforatecylinder disposed within said tube.

2. A device of thev character described comprising a tube, apressure-Huid supplypipe connected therewith, a nozzle disposed betweensaid tube and pipe, a chamber adjacent said nozzle, a pipe extendingfrom said chamber adapted to convey thereto the substances to beemulsiiied, and a perforate cylinder disposed within said tube having aroughened interior surface. v

3. A device of the character described comprising a tube, apressure-fluid supplypipe connected therewith, a nozzle disposed betweensaid tube and pipe, a chamber adjacent said nozzle, a pipe extendingfrom said chamber adapted to convey thereto the substances to beemulsied, a perforate cylinder disposed within said tube, and a stopperremovably secured at one extremity of said cylinder.

4. A device of the character described comprising a tube, apressure-fluid supplypipe connected therewith, a nozzle disposed betweensaid tube and pipe, a chamber adjacent said nozzle, a pipe extendingfrom said chamber adapted to convey thereto the substances to beemulsified, a perforate cylinder disposed within said tube, and meansfor preventing the displacement of said cylinder;
